[--norc] [--hp | --nohp]
[--debug | --nodevbug]
[--c-stack size] [--lisp-stack size]

DESCRIPTION

ECL (Embeddable Common-Lisp) is an interpreter of the Common-Lisp language as described in the X3J13 Ansi specification, featuring CLOS (Common-Lisp Object System), conditions, loops, etc. plus a translator to C, which can produce standalone executables. ECL supports the operating systems Linux, FreeBSD, NetBSD, OpenBSD, OS X, Solaris and Windows, running on top of the Intel, Sparc, Alpha, PowerPC and ARM processors.

The current ECL implementation features:

•   A bytecode compiler and interpreter.

•   Compiles Lisp also with any C/C++ compiler

•   Can build standalone executables and libraries

•   ASDF, Sockets, Gray streams, MOP, and other useful components

•   Extremely portable

•   A reasonable license

ecl without any argument starts the interactive lisp session.

OPTIONS

-?, --help
    Shows the help prompt without running the ECL.

--norc
    Do not load configuration files at startup.

--version
    Prints the current version of ECL, without running the ECL.

-debug
    Turned on by default, this enables the debugging in the setup phase, so that you can debug your files.

--nodebug
    Run without debugging setup phase, meaning that errors prevent ECL from starting up.

--eval file
    Evaluate the file before loading the .rc file and starting the Top Level.

--shell file
    Executes the given file and exits, without providing a read-eval-print loop. If you want to use lisp as a scripting language, you can write #!${exec_prefix}/bin/ecl --shell on the first line of the file to be executed, and then ECL will be automatically invoked.

--load file
    Load source file before loading the .rc file and starting the Top Level.

--dir directory
    Use directory as a system directory.

--heap-size size
    Specify heap size in kilobytes.

--lisp-stack size
    Specify stack size in kilobytes for bytecodes interpreter.

--frame-stack size
    Specify frame stack size in kilobytes for runtime control structures.

--c-stack size
    Specify stack size in kilobytes for C compiler.

--trap-fpe
    Make ECL debugger catch floating point exception.

--no-trap-fpe
    Make ECL debugger not catch floating point exception.

--encoding encoding
    Specify the external encoding for standard input, output, trace and error.

--input-encoding encoding
    Specify the external encoding for standard input.

--output-encoding encoding
    Specify the external encoding for standard output.

--error-encoding encoding
    Specify the external encoding for standard error.

-o file
    Provide the output target file for compilation.

-c cfile
    When compiling name the intermediary C file cfile and do not delete it afterwards.

-h cfile
    When compiling name the intermediary C file cfile and do not delete it afterwards.

--data [datafile]
    Dumps compiler data into datafile or, if not supplied, into a file named after the source file, but with .data as extension.

--compile file
    Translates file to C and invokes the local C compiler to produce a native code program.

-q  Short for quiet - produce less notes.

--hp
    This option is deprecated and doesn't do anything.

--nodp
    This option is deprecated and doesn't do anything.

-s  Produce a linkable object file. It cannot be loaded with load, but it can be used to build libraries or standalone executable programs.

AUTHORS
The original version was developed by Giuseppe Attardi starting from
    the Kyoto Common Lisp implementation by Taiichi Yuasa, Masami Hagiya. Further development was lead by Juan Jose Garcia Ripoll. The current maintainer of ECL is Daniel Kochmański, who can be reached at the ECL mailing list.

FILES

~/.ecl, ~/.eclrc
    Default initialization files loaded at startup unless the option --norc is provided. (if they exist).
